Emarginate Leaf Apex

The apex of the leaf is notched downward (towards the petiole) at the midvein. In the case of the Five-leaved Akebia, every leaflet is notched on this compound leaf.

The Umbrella Pine is included in this example, because it is a less obvious selection of an emarginate apex. It can only be observed on close inspection, but is a prominent identification characteristic.
